Centralized Weighing Pan Batch Dosing

Dosing for Multi Ingredient Recipes & High Accuracy Weighing

Central Weigh Hopper Batching is an automated gravimetric dosing concept in which multiple ingredients are sequentially dosed and weighed in a single weigh hopper according to the selected production recipe. This configuration is particularly suitable for batch processes requiring high weighing accuracy and repeatable formulation control. Each ingredient is dosed to its target weight using a two-stage feeding sequence coarse feed followed by fine feed. As the target weight is approached, the system switches to fine dosing for precise final weight control and automatically stops feeding once the defined tolerance is achieved. After all recipe components have been weighed, the complete batch is discharged to the mixer or transferred to the next process stage.

| System Configuration & Plant Layout

Raw materials can be supplied from bag dump stations, big bag unloading units, day bins, storage silos or pneumatic conveying receivers arranged around the central weighing point. Each ingredient is sequentially fed into a common weigh hopper according to the selected production recipe. By combining multiple ingredients within a single weighing system, this configuration provides high weighing accuracy and repeatability while reducing the number of weighing assemblies required.

• Compact and space-efficient system layout
• Single high-accuracy weighing point for multiple ingredients
• Reduced number of load cells and weighing assemblies
• Flexible integration with upstream material handling systems
• Coarse Dosing — High feed rate for rapid approach to the target weight
• Fine Dosing — Reduced feed rate for accurate final dosing
• Tolerance Control — Automatic cut-off when the defined weighing tolerance is achieved
• Batch Discharge — Automatic transfer of the completed batch to the mixer, vacuum receiver or downstream process

| Ingredient-Specific Feeding Technology

Reliable batch accuracy begins with controlled and consistent feeding. The appropriate dosing equipment is therefore selected individually for each ingredient according to bulk density, particle size, flowability, required feed rate and target accuracy. Depending on the application, the central weigh hopper can be supplied through screw feeders, rotary valves, gravity-fed dosing valves or vibratory feeders. This ingredient-specific approach ensures stable material feeding and repeatable weighing performance across powders, granules, pellets and other bulk solids with widely differing flow characteristics.

| Parallel Batching for Higher Throughput

For applications requiring short batch cycles or simultaneous feeding of multiple production lines, the system can be configured with multiple weigh hoppers operating in parallel. Tilting or rapid-discharge weigh hopper concepts can also be incorporated where short discharge times are required.

• Parallel preparation of multiple batches
• Simultaneous supply to multiple mixers or production lines
• Independent recipe execution where required
• Reduced batch cycle times
• Flexible configuration for future capacity expansion

_ Automation & Control

PLC-based recipe management, SCADA supervision, batch reporting and optional MES/ERP connectivity provide centralized control, production transparency and complete batch documentation

| Recipe Control & Batch Traceability

The complete batching sequence is automatically managed by the PLC control system. Target weights, ingredient sequences, dosing tolerances and process parameters are defined within the selected production recipe, enabling consistent and repeatable batch execution with minimal operator intervention. Actual weights, deviations, batch times, alarms and process events can be recorded and transferred to the SCADA, MES or ERP environment, providing comprehensive production reporting and batch traceability.

• Individual target weights and tolerances for each ingredient
• Automatic dosing sequence control
• Actual versus target weight monitoring
• Batch data recording and production reporting
• Alarm and deviation management
• SCADA, MES and ERP integration
